Nutrien Will Close Florida Phosphate Plant as Sulfur Costs Crush Margins
Nutrien plans to close its White Springs phosphate operation in Florida in the second quarter of 2027 after a strategic review concluded that the higher-cost site was approaching depletion of its mine reserves. The decision was disclosed with the company's third-quarter results on 4 November 2026. It is a scheduled closure next year, not an immediate shutdown.
The move reduces Nutrien's U.S. phosphate footprint to its core Aurora operation in North Carolina and regional upgrading facilities. For fertilizer buyers, the immediate question is not simply the loss of one plant, but how much rock, phosphoric acid and finished-product output can be shifted to Aurora without reducing supply or raising delivered costs.
White Springs supplied 23% of Nutrien's mined phosphate rock
Nutrien's 2025 annual filing shows that White Springs produced 1.39 million tonnes of phosphate rock last year, while Aurora produced 4.66 million tonnes. White Springs therefore accounted for about 23.0% of the 6.05 million tonnes produced across the two mines. This is an Agrilinkage calculation from company-reported production, not a forecast of the volume that will disappear after closure.
The same filing lists White Springs annual capacity at 2.0 million tonnes of phosphate rock, 0.5 million tonnes of phosphoric acid measured as P2O5, 0.7 million tonnes of liquid products and 0.8 million tonnes of solid fertilizer products. Actual 2025 output was below those nameplate levels. Nutrien has not disclosed a post-closure product-by-product supply plan or quantified how much volume Aurora will absorb.
Nutrien says it will optimize Aurora, which it describes as one of its largest phosphate operations. Its phosphate business page identifies White Springs and Aurora as the company's two large integrated U.S. phosphate sites. Concentrating production can lower fixed costs, but it also places more of the company's domestic phosphate system on a single integrated mine and processing complex.
Sulfur inflation erased almost all quarterly phosphate earnings
The closure decision arrived after Nutrien's phosphate adjusted EBITDA fell 93% year on year to $8 million in the third quarter. Cost of goods sold reached $939 per tonne, with the company pointing to sulfur inflation. Sulfur is a critical input for making sulfuric acid, which is then used to convert phosphate rock into phosphoric acid and fertilizer products.
That cost chain explains why strong fertilizer prices do not automatically produce strong phosphate margins. A producer can face higher selling prices while losing the benefit to sulfur, ammonia, energy and conversion costs. White Springs also faces a structural issue that pricing cannot solve indefinitely: the available mine reserve is nearing depletion.
$430 million impairment, plus a separate Trinidad charge
Nutrien expects a fourth-quarter impairment charge of about $430 million against the White Springs carrying value. It also expects a separate $760 million impairment connected with its already idled Trinidad nitrogen operations. Together, the two actions imply about $1.19 billion of anticipated impairments, but they concern different businesses and facilities.
The accounting charges do not equal the cash cost of closing the sites. Nutrien has not yet disclosed the White Springs cash closure cost, employee impact, reclamation schedule or product-transfer expense. Mining and phosphogypsum-stack obligations can continue after production stops, so the operational exit will extend beyond the final shipment.
What the closure means for fertilizer supply
White Springs makes products used in crop nutrition and industrial applications, including monoammonium phosphate and liquid phosphate products. Closing it will remove operating flexibility from Nutrien's network. The actual market effect will depend on Aurora utilization, inventories, imports, product mix and demand when the plant exits.
A simple one-for-one subtraction of White Springs nameplate capacity would overstate the likely supply loss because the site was running below capacity and Nutrien intends to optimize Aurora. Assuming there will be no effect would be equally premature because the company has not published a full replacement plan. Buyers should watch production guidance, Aurora reliability, phosphate sales volumes and regional freight patterns through 2027.
What happens next
The key checkpoints are the exact closure date, workforce and contractor plans, environmental and reclamation provisions, and Nutrien's 2027 phosphate sales guidance. The company will also need to show whether concentrating production improves margins without sacrificing customer service.
Agrilinkage reviewed Nutrien's 4 November results release, its 2025 annual regulatory filing and its current phosphate-business description. The 23.0% production share and $1.19 billion combined impairment figure are Agrilinkage calculations from disclosed amounts. Forward-looking closure and optimization statements remain company plans.
